Update README as only Conga 5290 is supported

After testing some of the devices identified as issues, we figured out
that this integration only works for Cecotec Conga 5290.

Changes:
* Repository name changed to Cecotec Conga 5290 integration.
* Add a table to better describe which vacuums are supported by this integration.
